LeAnn Rimes has long been an advocate for cancer causes. In 2008 she sang on the song, “Just Stand Up,” which raised money for Stand Up to Cancer and the American Association for Cancer Research. And earlier this year, she joined Anthony Anderson on a tune encouraging women to get breast exams called, “Treasured Chest.”

Mammography’s like photography but just for your breastsFor the best shot they’ll need them compressed—squeeze!—between two plates, then they’ll snap some x-rays

Now, Rimes is baring all in an effort to remind women to get checked for breast cancer. Rimes shared a sexy photo to Instagram saying, “Every 19 seconds, someone in the world is diagnosed with breast cancer. Each year, the survival rate is increasing thanks to early diagnosis. Let’s keep this going and raise as much awareness as possible for #NoBraDay2017#BreastCancerAwarenessMonth“

Don’t worry– it’s not all sexy, Rimes also shared a helpful chart on breast exams.
